I guess it depends on where you look ..No wonder NHRA is confused on this subject.


GM upgraded the 4L60 to electronic control with the 1993 model year and these transmissions were used in a wide variety of applications from the Camaro and Corvette to full size cars and light and medium duty trucks. The big improvement was total electronic control which eliminates the need for the troublesome TV cable and also did away with the spinning weights and springs used in the governor, since input and output speeds are now measured by sensors and the up and down-shifts are controlled by an electronic transmission controller.

GM started adding electronic controls to the 4T60 in 1990 with the Cadillac Allante carline's unique F7, and 1991 and after with the corporate 4T60-E.
